As amended, the definition of “First Trial Milestone” shall read in relevant part as follows: “. . . . the date when either, pursuant to predetermined criteria reviewed by the Board (i) the primary endpoints of the Company’s anticipated Phase IIb clinical trial of the Company’s nitric oxide/plasma product are achieved such that the Company may proceed to Phase III trials or (ii) U.S. Food and Drug Administration approves an Investigational Device Exemption that permits the Company to proceed directly to pivotal (Phase III) trials without the need for a pilot (Phase IIb) trial (the “First Trial Milestone”)”.

2. No Further Amendment. Except as amended hereby, the Employment Agreement shall remain unmodified and in full force and effective.

3. Governing Law. This Amendment shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed in that state, without regard or reference to its principles of conflicts of laws.
